A SI is not going to tell you much in respect to doing speed events such as Barrels or pole. A SI is a racing rating showing how fast a horse was on a given track. A SI on one track will be different then one on a different track. It also will vary from distance to distance.
Speed event have more to do with rating and turning then out and out speed. You can have the fastest horse in the world but if he can not rate his speed and turn it will make no difference.
